Benefits of technology

[0022]According to the present invention, a magnetic data eraser (or a magnetizing apparatus or a degaussing apparatus) is provided, which eraser is capable of performing data erasing process in which data of magnetic recording medium such as a hard disk drive (HDD) is erased easily and capable of performing the magnetic data erasing process with reduced electric power.

Problems solved by technology

Therefore, there has been needed to take a longer time and complex operations to perform data erasing process for erasing date stored in a magnetic recording medium by using a conventional data eraser.

first embodiment

[0033]FIGS. 1a-1d are diagrams for explaining structure of a magnetizing apparatus (a magnetic data eraser) for magnetizing a magnetic recording medium according to a first embodiment of the present invention. FIG. 1a is a front view of the magnetizing apparatus,

[0034]FIG. 1b is a side view of the magnetizing apparatus, FIG. 1c is a back view of the magnetizing apparatus, and FIG. 1d is a top view of the magnetizing apparatus.

[0035]In FIGS. 1a-1d, the magnetizing apparatus 1 that also may serve as a magnetic data eraser for erasing date stored in the magnetic recording medium is configured to have a magnetizing coil (forming portion) 2 and a hollow body portion 3 to which a holding drawer (or a holding drawer means) for holding a magnetic recording medium is accommodated or mounted, although the holding drawer will be discussed below in more detail. The magnetizing coil 2 is made from a number of turns of winding, and ends of the winding (wire) are connected to an electric current s...

second embodiment

[0055]A second embodiment of the present invention will be discussed below.

[0056]The second embodiment discloses an invention that provides other configuration of a holding drawer that is to be mounted within the magnetizing apparatus 1 than those disclosed in the first embodiment, and in explanation of the present embodiment, a hard disk drive fixing tray (fixture) (or a holding drawer means) (herein after it will be referred to as a “HDD fixing tray”) will be used instead of the holding drawer that has been discussed previously to hold a hard disk drive.

[0057]FIG. 3 is a perspective view of a HDD fixing tray according to the second embodiment of the present invention viewed from a front side. Further, FIG. 4 is a perspective view of the HDD fixing tray according to the second embodiment of the present invention viewed from a left side. In both of the figures, a mounting tray 21 is fixed to a HDD fixing tray 20, and a hard disk drive is placed on the mounting tray 21. The mounting ...

third embodiment

[0070]Next, a third embodiment of the present invention will be explained.

[0071]In the present embodiment, a confirmation of completion of erasing data stored in hard disk drive (HDD), i.e., a magnetizing or a degaussing the hard disk drive, would be carried out by using an image sensor (capturing means for capturing an image of the magnetic recording medium) that is provided in the magnetic data eraser (or a magnetizing apparatus or a degaussing apparatus) for capturing an image of the hard disk drive (HDD).

[0072]FIG. 5 shows a magnetizing apparatus to which the image sensor 30 mentioned above is installed. Specifically, the image sensor 30 is installed in the HDD fixing tray 20 to capture an image of the hard disk drive (HDD) from above and behind, wherein the hard disk drive (HDD) is secured to the HDD fixing tray 20. A Charge Coupled Device (CCD) sensor, a Complementary Metal Oxide Semiconductor (CMOS) sensor, and the like can be used as the image sensor 30, and a captured image...

Abstract

The present invention relates providing a magnetic data eraser that is capable of performing magnetizing process for magnetizing magnetic recording medium such as a hard disk drive (HDD) is easily and with reduced electric power.The magnetic data eraser includes: holding drawer means for holding a magnetic recording medium which means has a mounting tray for mounting the magnetic recording medium, wherein the mounting tray is inclined a predetermined value of degrees of angle; and magnetizing means for magnetizing the magnetic recording medium, wherein the magnetizing means is covered by a magnetizing coil and has a hollow body portion, the holding drawer means being accommodated in the hollow body portion, and the magnetic recording medium being placed on the mounting tray of the holding drawer means.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application is based on and claims priority from Japanese Patent Application Number 2010-109909, filed May 12, 2010, the disclosure of which is hereby incorporated by reference herein its entirety.BACKGROUND OF THE INVENTION[0002]1. The Field of the Invention[0003]The present invention relates to a magnetic data eraser that is configured to erase magnetic data stored in a magnetic recording medium such as a hard disk drive.[0004]2. Description of the Prior Arts[0005]Nowadays, when a magnetic disk drive (hereinafter, it is exemplified by a hard disk drive) is intended to be discarded after it has been finished to be used in an office of a company or by an individual person, magnetic data should be erased by formatting the hard disk drive, for example, upon a request from an operating system in a computer while the hard disk drive is connected to the computer, in order to conceal the magnetic data stored in the hard disk drive fr...
